SYRINGE.

SPECIFICATION forming part of Letters lPatent No. 653,013, dated July3,1900.

Application flled April 2, 1900.

To all whom/,it may conc/7%.-A

`Be it known that I, WILLIAM A. ARMOUP., of Thomaston, in the county ofLitchfield and State of Connecticut, have invented a new Improvement ina CombinedSpeculum and Syringe; and I do hereby declare the following,when taken in connection with the accompanying drawings and the lettersof reference marked thereon, to be a full, clear, and exact descriptionof the same, and which said drawings constitu te part of thisspecification, and represent, in-- Figure 1, a side view of a combinedspeculum and syringe constructed in accordance with my invention,showing the partsin their contracted position; Fig. 2, a similar viewwith the speculum-blades open; Fig'. 3, a broken vertical sectionalView; Fig. 4, a side view of the nut detached; Fig. 5, a side view ofthe upper end of the slide; Fig. 6, abroken sectional view illustratinga modification of the manner of connecting the speculumblades with thebody; Fig. 7, asectional'view illustrating further modifications.

This invention relates to an improvement in a combined speculum andsyringe, and particularly to that class in which the arms or blades ofthe speculum are adapted to be expanded by a moving part of the device,the object of the invention being a simple construction which readilypermits the arms or blades to be positively moved and held in thedesired position; and it consists in the construction as hereinafterdescribed, and particularly recited in the claims.'

Preferably the device will consist of a body A and, for the purpose aswill hereinafter appear, what I will term a nut B, the said nutextending upward through the body A and formed with a slot b, adapted toreceive the end of a screw C, which extends through one side of the bodyinto said slot, whereby the body and nut are swiveled together. Y Theupper end of the nut is formed with cam-surfaces D, adapted to engagewith pins E on a tubular slide F', the said slide being formed with adisk G, having beveled edges g and a threaded nipple I-I at its upperend, while its lower end, which extends through the'nut, is adapted tobe connected with asupply-pipe. (Not shown.) To the nipple'H thedischargetube I, which may be of any approved con- Serial No. 11,042.(No model.)

struction, is attached. To the upper face of the body A three or moreplates J are secured, the ends of the fingers K of which project throughslots L, formed in the lower ends ot' the speculum-blades M. Thesefingers K are preferably turned into substantially-circular shape, so asto permanently secure the blades to the body; but it is evidentthat theymay be' left partially open, as shown in Fig. G, and so that the bladesmay be readily removed. The lower ends of these blades are inclinedinward, so as to bear against the inclined surfaces g of the disk G, andwhereby the Vertical movement of the disk will expand the outer ends ofthe blades. l

Instead of forming the nut with the camsurfaces D and having the nutextend through the plate the nut may be swiveled to the plate, as shownin Fig. 7, in which the nutis formed with an angular groove N, intowhich two or more arms O extend, the arms being secured to the underface of the body.A With this construction the nut will be internallythreaded and the tubular slide Fexternally threaded for engagementtherewith and so that by turning the nut the tubular slide will be movedinward or outward.

Instead of attaching the discharge-nozzle to the slide, as abovedescribed, it may be made of proper size to extend through a centralopening formed in the slide, as also shown in Fig; v7, thus permittingthe tube to be projected to a greater or less extent above the disk.

In the construction first described the rotation of the nut B causes thecam-surfaces D to ride under the pins E, and thus force the slideupward, and this upward movement of the slide carries the disk againstthe lower ends of the blades L and f orcestheir upper ends outward, asshown in Fig. 2, whereas the reverse movement of the nut permits thedisk to be forced downward and the blades contracted. If the threadednut is employed,

the turning of the nut operates in the same?v IOO` bined withspeculuni's, and whereby a movement of one part will expand or contractthe blades of the speculum, and therefore do not wish to be understoodas claiming, broadly, such as my invention; but,

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The herein-described combined speculum and syringe, consisting of abody, a nut swivelly connected therewith, a slide extending through saidnut and adapted to be longitudinally moved by the rotation of the nut,said slide formed at its upper end with a disk, speculum-arms secured tosaid body, and having inclined ends adapted to bear against said disk,and a discharge-nozzle carried by said slide, substantially asdescribed.

2. The herein-described combined speculum and syringe, consisting of abody, a nut extending through said body and swivelly connected therewithand formed at its upper end with cam surfaces, a slide extending throughsaid nut, and having studs for engagement with the said cam-surfaces,whereby the movement of the nut will force the slide upward, a diskcarried by said slide, speeulum arms secured to said body, and adaptedat their lower ends to bear upon the edges of said disk, and adischarge-nozzle carried by said slide, substantially as described.

3. The herein-described combined speculuin and syringe, consisting of abody, a nut swivelly connected therewith, a slide extending through saidbody, and adapted to be longitudinally moved by the rotation of saidnut, a disk at the upper end of said slide, a discharge-nozzle extendingthrough said slide, and speculum-arms pivotally connected with said bodyand adapted to bear upon the edge of the said disk, substantially asdescribed. In testimony whereof I have signed this specification in thepresence of two subscribing witnesses.
